When can liquor be unlocked when departing from Mexico?

Liquor can be unlocked after takeoff when departing from Mexico due to regulations established by both Mexican aviation authorities and international aviation policies. Once the aircraft is airborne, the flight crew is authorized to serve alcoholic beverages in accordance with safety and operational protocols. This is aligned with the context that once an aircraft has taken off, it transitions to international airspace, where different rules about serving alcohol apply compared to when on the ground or preparing for departure.

Prior to takeoff, alcohol cannot be served or consumed on board due to restrictions aimed at maintaining order and safety during critical phases of flight. This ensures that passengers remain calm and compliant with safety protocols while the aircraft is taxiing and preparing for departure. Serving liquor on the ground, also brings in factors regarding customs and safety regulations that are more restrictive compared to the policies enacted once the aircraft is in the air.

Since serving alcohol is restricted to after takeoff in this scenario, it emphasizes the importance of adhering to safety guidelines in the aviation environment.
